The most stunning news of the NBA’s offseason had nothing to do with a free-agent signing, a blockbuster trade or a front-office restructuring. After 24 years of ownership, Leslie Alexander is putting the Houston Rockets up for sale, a shocking development announced Monday that promises to reverberate throughout the basketball world.

“It’s been my great joy and honor to own the Houston Rockets for the past 24 years,” Alexander said in a team statement. “I’ve had the incredible opportunity to witness true greatness through the players and coaches who have won championships for the city, been named to All-Star and All-NBA teams, enshrined in the Basketball Hall of Fame, and done so much for our franchise and our fans.”
